Section 3.1: Understanding Rational Exponents and Radicals

Objective: By following instructions, students will be able to: Determine how radicals and rational exponents are related.

Formulas Words Any non-zero number raised to the power of 0 is 1. 00=undefined And integer n. Any non-zero number raised to a negative power is equal to 1 divided by the same number raised to the opposite, positive power. Examples

n=index, must be greater than 1 a= radicand Power of a Power Property Rational Exponent

Find the root and simplify the expression. explain 1A

Find the root and simplify the expression. explain 1b

Your-Turn #1 Find the root and simplify the expression. a) b)

explain 2A Simplify the expressions with rational exponents.

explain 2B Simplify the expressions with rational exponents.

Revisit Objective: Did we... Determine how radicals and rational exponents are related?
